摘　　要：采用均相反应界面生长法成功地制备了多种形貌的纳米铜,讨论了界面生长法制备纳米粒子的机理,考察了界面生长及反应温度的改变对产物形貌的影响.并用扫描电镜、透射电镜、X-射线粉末衍射等分析测试技术对样品进行了表征.A method, homogeneous reaction and interface growth, has been used to fabricate nano - materials. Copper nanoparticles with different morphologies have been prepared by liquid - liquid interface growth in the presence of Polyvinylpyrrolidone and the mechanism of interface growth has been discussed in this paper. The effect factors, such as interface growth and reaction temperature, have been investigated. The products have been characterized with transmission electron microscopy （TEM）, scanning electron microscopy （SEM） ,X - ray diffraction（ XRD）, and ultra - violet - visible（ UV - Vis）.
